## Abstract

The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect approval of two new animal drug applications (NADAs) filed by Elanco Animal Health. One NADA provides for use of ractopamine and monensin Type A medicated articles to make dry and liquid two-way combination Type B and Type C medicated feeds for cattle fed in confinement for slaughter. The other NADA provides for use of ractopamine, monensin, and tylosin Type A medicated articles to make dry and liquid three-way combination Type B and Type C medicated feeds for cattle fed in confinement for slaughter.
